T 0 all/whom t may concern.'

Be it known that l, SIDNEY B. MERRILL, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gongs, of which the following is a full, clear, andA exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to gongs such as are used in schools and factories for signaling purposes.

Fire gongs, class or period gongs, and gongs to signal change of Working shift in factories and shops, have been developed in the past and, particularly in connection with re gongs, must be carefully constructed so as to be easy and positive of operation.

Alnong other things, many gongs are so arranged that they are operated on several i'ioors of a building and several places on each floor. A gong hard to operate may become impossible for a child or weakened person to work, and thus ineffective at the time of greatest need.

ln the location of gongs in a series on different floors it is a great advantage to have them so conned in lateral dimensions that they can be set on a narrow vertical beam or upright on each floor. @ne of my objects is to provide a gong in which units can be set one above the other and a mount ing space of around three or four inches in width, all that is required for each unit.

One of the objects of my invention is to provide a gong which operates on a laterally pulled handle and which accordingly will not be broken, as by a careless person placing his whole weight on the handle, or a child hanging on it in play.

Another ofthe objects of my invention is to provide a gong operating device which lies along the center line of the gong itself, thereby cutting down the Width of any installation.

Another object is to provide an effective mode of operation of the gong itself from a shaft, said shaft being a rock shaft and thus capable of being connected up with yother gongs on the same floor by means of arms on the operating shafts of each bell and a wire of rod connecting the arms.

These various objects and other advantages to be noted l accomplish by that certain construction and arrangement of parts to be hereinafter more specically pointed out and claimed.

in the drawings,

i Figure l is a front elevation of the gong operating device with the lines of the gong illustrated.

Figure 2 is a side elevation of the gong.

A. casting l is provided as a mounting for the device, this casting having three vshaft bearings 2, 3 and 4, in which lies a shatt 5. @n each end of the shaft 5 located outside of the casting is a standard connecting sleeve 5at having threaded holes therein, into which the shaft 5 is screwedor pinned and into which connecting shafts 6 are screwed.

Any one of the shafts 6 in a system of bells or gongs arranged according to my invention may have a handle 7 thereon, which is pulled laterally to rock the shaft upon which it is located. This shaft will rock the shafts 5 of each unit in a vertical line. Also any two shafts 6 or 7 may be connected together by means of an arm 8 on each shaft and a wire or rod 9 connecting the arms. f

Thus in setting up a set of gongs in a building, some wall is chosen which runs vertically through the building and the gongs are set on each floor in position directly above each other. The shafts or rods 6 are then secured in the sleeves at the top and bottom of each gong and the handle arranged on the shaft most convenient for operation.

For a number of bells on one floor the gong castings are mounted as desired, and an am and wire connection made as above note The device for operating the gong is dei signed for ease of operatlon and positive action.

rlhe clapper or striker 10 is mounted on 1 a pivot stud ll on the casting,-and has a laterally extending arm 12. A spring 1,3 is connected to the striker bar and tends to pull it towards striking position. A

stop 13ZL retains the arm in position suoli l the p, enough inoinentuui will be at quired by the need to enable it to the gong by reason or looseness oit the zii-in bearing and resilience in the arni.

To trip the striker a rocker le is provided pivoted in the boss 15 of the casting, this rocker carrying a pawl 16 that contacts with the end of the arm l2. This pavvl is heid in position in a bifuroated end or" the rocker by means of a spring- 17, suoli that it will push up on the end of the arin l2 and then snap past the end ot the arrn, permitting` it to move down freely. @n the return ot t ie rocker under intiuenee of its own spring,- i8, the pawl Will snap under the end ot the arrn l2 The boss l5 mounts on its outer end the rgong member To operate the rocker it is provided wit i t depending,` arm 2G and a dog 2l is mounted on the shaft 5 by means of a collar 22 in such a position that when the shaft 5 is rocked, the dog` will contact With the arin 20 and push it over.

The .springthat pulls the rocker back to normal posit-ion Will also return the shaft 5, since the dog does not pass beyond the irin 20.

By entf-:riding1 the operating` handle 7 and because o'l" the lever at vantage in the rocker and arin device, it does not take inuoh strength to operate the gong and a child can operate a series ot' theni on oiterent floors or a. school building- Without any trouble.

The nietliod of Construction of the sounding apparatus and the exact structure of the coniieetions are not insisted upon by ine, and l do not desire the claims that folloW to be limited because of my failure to point out alternative structures, which l dee-in to come within the spirit of said claims.

ving thus described my invention, what @"in as new and desire to secure by Letters latent, is

1. ln a device of the character described, traine, a gong ounted thereon, a` gong trikeig rook s rait mounted on the traine at right angles to the anis oi" the gong, end tripping` device mounted on the frame and perated by the rock shaft for operating the striker.

2. 'A gong system conirrising a series of gongs, trames upon which said gongs are severally mounted, gong` strikers for each gong, with tripping` devices lt'or each striker, and a oontiniirous rigid linear member mounted to rook on its longitudinal axis, said linear nieinber having devices thereon to operato the. sti'kers for each gongwhen the linear member is rocked.

3. ln a device of the character described, a mounting trarne, a gong mounted thereon, a rooker mounted bet-Ween the gong and the traine, a gong" striker adapted to be tripped by the rocker and mounted on the frame, a rock sha t mounted on the traine behind the gong nd extending` lengthwise of the trame, and inc-.ans on the shaft to actuate the rocker, whereby the entire device is located Within the confines ot the gong,

4i. ln a device. ot the Character described, the ,combina-tion ot a. mounting trarne, a shaft extending lengthwise of said traine, a gong mounted on the frame, a rocker rnounted between the gong` and frame so as to rock at right angles to the shaft, adog on the shaft to aotuate the rocker upon a rooking of the shaft, a striker for the gong positioned on the frame between the gong and traine, said rocker adapted to trip the striker to enable it to tap the` gong, as and for the purpose described.
